"It was so quick, heard a pop, I thought it was fireworks. Just that quick, he was gone," said Firefighter Anthony Scuito.
The shooting happened across from Chicago Fire House 81. Firefighter Anthony Scuito was among the first to respond.
"I was walking out of the fire house, and all of a sudden I heard a pop, so I thought somebody was blowing fireworks. As I turned the corner, I saw the girl screaming and the cop pulled up. I didn't see the car pull away or nothing," said Scuito.
Also around 11 a.m. Friday morning in the South Deering neighborhood was Sal Flores. He was about to mow his lawn when he heard the shot.
"Nowadays, it seems like i hear one every day," said Flores.
Chicago police are looking for a four-door, full-size Chevy. It is described as an early 1980s model. It is black with red doors.
Police say the victim was 38-year-old George Cruz. ABC7 spoke with Cruz's brother Monday. He said they are trying to come up with the funds to bury George.
In the meantime, police urge any motorist who is confronted by an aggressive driver to call for help or go to the nearest police station.
